random FlushRelationBuffers() failed on Pg8.0.1 Win32

PG version =
"PostgreSQL 8.0.1 on i686-pc-mingw32, compiled by GCC gcc.exe (GCC) 3.2.3
(mingw special 20030504-1)"

Attached is the regression result of my test on Pg8.0.1 win32. The problem
is quite random. On the second round, it just disappeared.
